The following is a list of changes: 1.) the state name is now included in the sysfs interface 2.) detection, hotplug, and available state modifications are handled by CPUIDLE drivers directly 3.) the CPUIDLE idle handler is only ever installed when at least one cpuidle_device is enabled and ready 4.) the menu governor BM code no longer overflows 5.) the sysfs attributes are now printed as unsigned integers, avoiding negative values 6.) a variety of other small cleanups Also, Idle drivers are no longer swappable during runtime through the CPUIDLE sysfs inteface. On i386 and x86_64 most idle handlers (e.g. poll, mwait, halt, etc.) don't benefit from an infrastructure that supports multiple states, so I think using a more general case idle handler selection mechanism would be cleaner.

I call it the 'menu' governor because it considers the full list of idle states before each entry. I've kept the implementation fairly simple. It attempts to guess the next residency time and then chooses a state that would meet at least the break-even point between power savings and entry cost. To this end, it selects the deepest idle state that satisfies the following constraints: 1. If the idle time elapsed since bus master activity was detected is below a threshold (currently 20 ms), then limit the selection to C2-type or above. 2. Do not choose a state with a break-even residency that exceeds the expected time remaining until the next timer interrupt. 3. Do not choose a state with a break-even residency that exceeds the elapsed time between the last pair of break events, excluding timer interrupts. This governor has an advantage over "ladder" governor because it proactively checks how much time remains until the next timer interrupt using the tick infrastructure. Also, it handles device interrupt activity more intelligently by not including timer interrupts in break event calculations. Finally, it doesn't make policy decisions using the number of state entries, which can have variable residency times (NO_HZ makes these potentially very large), and instead only considers sleep time deltas. The menu governor can be selected during runtime using the cpuidle sysfs interface like so: "echo "menu" > /sys/devices/system/cpu/cpuidle/current_governor" Signed-off-by: Adam Belay <abelay@novell.com> Signed-off-by: Len Brown <len.brown@intel.com> commit a4bec7e65aa3b7488b879d971651cc99a6c410fe Author: Adam Belay <abelay@novell.com> Date: Sat Mar 24 03:47:03 2007 -0400 cpuidle: export time until next timer interrupt using NO_HZ Expose information about the time remaining until the next timer interrupt expires by utilizing the dynticks infrastructure. Also modify the main idle loop to allow dynticks to handle non-interrupt break events (e.g. DMA). Finally, expose sleep ticks information to external code. Thomas Gleixner is responsible for much of the code in this patch.

This is due to enter_idle(), exit_idle() races. Make cpuidle_idle_call() confirm to this when there is no pm_idle_old. Also, cpuidle look at the return values of attch_driver() and set current_driver to NULL if attach fails on all CPUs.

A cpuidle driver can support multiple idle states based on parameters like varying power consumption, wakeup latency, etc (ACPI C-states for example). A cpuidle governor can be usage model specific (laptop, server, laptop on battery etc). Main advantage of the infrastructure being, it allows independent development of drivers and governors and allows for better CPU power management. A huge thanks to Adam Belay and Shaohua Li who were part of this mini-project since its beginning and are greatly responsible for this patchset. This patch: Core cpuidle infrastructure. Introduces a new abstraction layer for cpuidle: * which manages drivers that can support multiple idles states. Drivers can be generic or particular to specific hardware/platform * allows pluging in multiple policy governors that can take idle state policy decision * The core also has a set of sysfs interfaces with which administrato can know about supported drivers and governors and switch them at run time.

Furthermore, rfkill expects the timeout as a value in milliseconds instead of jiffies. Also increase the timeout to a second, since this 250ms would be overkill. Also the flag DEVICE_ENABLED_RADIO_HW is causing problems for devices which do not support the hardware button while rfkill is enabled in the driver. To remidy this we should inverse the flag and its meaning, rename the flag to DEVICE_DISABLED_RADIO_HW this means that by default the radio is enabled by the hardware button (if present) and can only be disabled explicitely.

* | [PATCH] ipw2200: batch non-user-requested scan result notificationsDan Williams2007-10-102-10/+49
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ipw2200 makes extensive use of background scanning when unassociated or down. Unfortunately, the firmware sends scan completed events many times per second, which the driver pushes directly up to userspace. This needlessly wakes up processes listening for wireless events many times per second. Batch together scan completed events for non-user-requested scans and send them up to userspace every 4 seconds. Scan completed events resulting from an SIOCSIWSCAN call are pushed up without delay.

* | [HOSTAP]: set netdev type before registering AP interfaceDaniel Drake2007-10-103-10/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As detailed at https://bugs.gentoo.org/159646 hostap with hostapd confuses udev by presenting 2 interfaces with the same MAC address. Also, at the time of detection, the 'type' attribute is 1, identical to other hostap interfaces. The AP interface is supposed to have type ARPHRD_IEEE80211 (801), but this is not set until after registration. Setting it before register_netdev() is called allows us to avoid this confusion. We can do this by propogating the HOSTAP_INTERFACE type through to hostap_setup_dev(). Signed-off-by: Daniel Drake <dsd@gentoo.org> Signed-off-by: John W.
